Lentiviral Tet-On 3G Inducible Expression Systems

The Lenti-X Tet-On 3G Inducible Expression Systems combine the broad cellular tropism of lentiviral gene transfer technology with the power and versatility of our state-of-the-art tetracycline-regulated gene expression system. The lentiviral Tet-On-3G system consists of two lentiviral vectors: a regulator vector that stably expresses the Tet-On 3G transactivator protein, and a response vector that contains the TRE3G promoter that controls the expression of your transgene. Also included are a control response vector for luciferase expression, and our premium Lenti-X Packaging Single Shots (VSV-G).

How it Works

Doxycycline-controlled “transactivators” are fusion proteins that contain a TetR-derived DNA binding domain joined to three minimal transcription activation domains from VP16 (Tet-On 3G). With very high specificity, the transactivator recognizes and binds to a Tetracycline Response Element (TRE) that is located in the PTRE3G promoter of pLVX-TRE3G, into which you clone your gene of interest. Binding of the transactivator to the TRE promoter results in strong activation of the downstream gene. Tet-On 3G is the premium 3rd generation version of the technology, with the tightest TRE promoter and most sensitive transactivator.

In Tet-On systems, gene expression is activated by the addition of Dox to the growth medium, while in Tet-Off systems, transcription is activated by its withdrawal.

Applications

Tetracycline-inducible expression in the widest range of hard-to-transfect cell types.
